MACHINE FOR MAKING WEAVERS" HARNESS.

SPECIFICATION forming part of Letters Patent No. 306,306, dated October 7, 1884 Application filed January 2, 1893. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH S. Wmson, of the city and county of Providence, and State of Rhode Island, have invented certain new and useful Improvements in Machines for Making Weavers Harness, of which the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part of this specification.

My invention relates to that class of machines which are described and claimed in Letters Patent No. 12,175, granted to me J anuary 2, 1855; and the invention relates more particularly to the switch-motion by which the movement of the twine-spools relative to the studs is controlled.

The object of my invention is to produce a simpler and more accurately-operating switclr motion than that described in my former patcut, above referred to; and to this end my invention consists in the peculiar and novel construction and arrangement-of parts, as hereina'fter described.

In order that my invention may be fully understood, I will now proceed to describe it with reference to the accompanying drawings, in Which-a Figure 1 is a plan View, partly broken away, of a portion of a machine for making weaver s harness,with my improvements applied. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a transverse vertical section of the same, and showing also the cam for operating the switch motion. Fig. a is a transverse vertical section of a portion or the machineframe on an enlarged scale, showing one of the spool-carriers and one of the geared carriers by which the former is moved. Fig. 5 is an enlargedview in horizontal section of a spoolcarrier engaged by a pair of the geared carriers, the two opposite positions of the switches being indicated in solid and in broken lines. Fig. 6 is a plan View of the switch mechanism.

In machines for making weavers harness, such as are described in my said former patent, four of the switches by which the direction of movement of the spool-carriers or travelers is changed are each operated by a separate cam, and for this reason it is difficult to so adjust the switches as to insure and maintain them in such relation. that they will direct the carriers invariably in their proper move ments. In order to avoid this defect, I connect two switches on each side of the machine to a bar, and connect the two switch-bars to a centrally-pivoted lever, so that the two switchbars and their four switches are operated simultaneously by connections wit-11 a single cam, whereby no repeated am adjustments are necessary, and whereby, also, the construction of the machine is simplified by dispensing with the cams shown in my said patent for operating three of the switches and three entire sets of operative connections therefor.

In the said drawings, A A designate the switch bars B B,the switches or switch-points; O, the centrally-pivoted connectinglever, and D the eam;lever. The cam lever D is connected at its upper end to either the lever C, as shown in Fig. 8, or with one of the switchbars A, and at its lower end the said lever is pivotally attached to the machine-frame.

At the point indicated in Fig. 3 the lever I) is provided with a pin or projection, d, which comes in contact with the cam E, which is mounted upona cam-shaft journaled 11orizontally in the machine-frame, and connected by suitable gearing with the driving-shaft of the machine, as described in my said patent. By this arrangement the four switches are operated simultaneously and are caused to guide the spools in the manner described in my previously referred to patent.

The gears or geared carriers II, for operating the spool-carriers or travelers F, as heretofore constructed, have been supported on spindles which have been each provided with a circular portion forming a part of the way through which the spool-carriers move. These spool-carriers or travelers have to be fre quently removed for cleaning and oiling, and

the gears and spindles have to be readjusted. after each such removal, which is a very ob-.

jectionable consequence of the former arrange ment.

In accordance with my invention I cast upon or otherwise secureto the plate I; the sleeves Z, so as to form a fixed center-for each of the geared carriers II. The sleeve Z is bored out to receive the spindle or stud m, and is trued so as to form a bearing for the gear H. Thus the spindle or stud m, with its center l,

e as also the gear II, can be readily removed.

which, by being tightened up, causes the under side ofthe center I on the stud to bear upon The plate 75 is secured in position upon the machine-frame directly under the plates F, which form the external portions of the ways for the spool-carriers. The centers I are keyed t0 the studs m, and serve thepurpose of forming the turning-points, together with the ways for the spool-carriers, as fully described in in v former patent. The studs m are each secured in place in the plate 7: by a nut, m, which is secured upon the lower end of the stud, and

the top of the sleeve Z by reason of the action of the nut 0n the lower end of the stud.

Having thus described my invention, I claim as new and desire to secure byLetters Patent" 1. The combination,with the spoolwarriers the centers, the geared carriers, and the plates forming the external portions of the spool- I carrier ways, of the switch -bars having the switclrpoints, the centrally-hinged connecting-lever, the hinged cam-lever provided with the pin, and the cam, all constructed and arranged to operate substantially as described. 2. The COIIlbll1ELtlOll,WllJh the spool-carriers, the studs, and the plates forming the external portions of the spool-carrier ways, of the plate k, the sleeves Z, and the geared carriers H, substantially as and for the purposes set forth.
